▎ 摘 要
We investigate the way that the degenerate manifold of midgap edge states in quasicircular graphene quantum dots with zigzag boundaries supports, under free-magnetic-field conditions, strongly correlated many-body behavior analogous to the fractional quantum Hall effect (FQHE), familiar from the case of semiconductor heterostructures in high-magnetic fields. Systematic exact-diagonalization (EXD) numerical studies are presented for 5 ]
